New Salamander Discovered Near Georgia Busy Road

A newly discovered salamander, which is the second-smallest salamander species in the U.S. and one of the smallest in the world at just two inches long, could change what scientists know about some amphibians, the University of Georgia Warnell School of Forestry and Natural Resources said today.

The new salamander is so distinct that it belongs in its own genus (a grouping of related species), according to Carlos Camp, Piedmont College professor who first recognized it as a news species. “It represents the first new genus of four-footed creature discovered in the United States in 50 years.”

Researchers weren’t looking for anything new when they went exploring in the northeast part of Georgia. “But they ended up making a big discovery of a tiny animal,” the University of Georgia said in a statement about the discovery.

The salamander is now under study by a diverse group of researchers from several U.S. colleges. The team is searching for more of the salamanders, which are described in a new paper appearing in the Journal of Zoology.

The initial discovery came in spring 2007 near Toccoa, Georgia, when University of Missiouri graduate student Bill Peterman and Warnell graduate student Joe Milanovich stumbled across it while collecting another species of salamander in Stephens County.

“They knew they’d found an animal not known in that region but did not yet know it was a new species,” Warnell said in the statement.

Milanovich consulted John Maerz, a Warnell assistant professor of wildlife, who advised the students to take the salamander to Carlos Camp, professor at Piedmont College, who recognized it as a new species. Trip Lamb, a professor at East Carolina University, used genetics to confirm the new species and establish its relationship to other species in the region.

After the students found the first salamander, a female with eggs, in a creek, researchers went back repeatedly looking for others, Warnell said. “That is when Maerz’s then 10-year-old son Jack and Milanovich found the first male specimen.”

The research team has since found several individuals at the original site, including larvae, and they have found the new species at two other nearby locations in Georgia. Collaborators also found the species at a nearby site in South Carolina, Warnell added.

Evolution of Stream Salamanders

This discovery, according to Maerz, could yield exciting new information on the evolution of stream salamanders in this region.

“Whenever you find something new, it has the potential to change what we know about a range of related species,” he said. There are more than 560 species of salamanders worldwide, and approximately 10 percent are found in Georgia.”

But that’s not the only reason Maerz is excited, Warnell added. “The new species was found in a well-traveled area in the middle of a creek right next to a road, almost hidden in plain sight.”

“To make such a find in an area with extensive human activity proves that there are still things out there to discover. It makes you wonder, what else is out there?”

“To make such a find in an area with extensive human activity,” Maerz said, “proves that there are still things out there to discover. It makes you wonder, what else is out there?”

With funding from The Environmental Resources Network (TERN), Milanovich and Camp are leading research efforts to describe the ecology of the tiny creatures.

“It is truly a once-in-a-lifetime opportunity to be involved in such a big find, particularly one right in our backyard,” Milanovich said. “The fact that it is such a unique animal makes it all the better and gives us more opportunity to continue to learn about the species. One of the best parts of being involved with this project is the collaboration that has come out of the species description, so I am excited to continue working with the other coauthors as we keep unpeeling the onion of U. brucei.”

Patch-nosed Salamander

The research team’s suggested common name is patch-nosed salamander, based on the lighter coloring on the tiny salamander’s nose. The formal Latin name is Urspelerpes brucei for Richard Bruce, professor emeritus at Western Carolina University and a well-respected, longtime salamander researcher who has connections to many members of the research team.

“Dr. Bruce has done much of the foundational work on stream salamander ecology in the region and on the evolution of miniaturization in salamanders, so naming this species after him is a good fit,” Maerz said.
